Caterpillar MD5075C Track Drill Offers Two Different Rock Drill Choices

December 1, 2015

The MD5075C track drill replaces the MD5075 and is capable of drilling holes of 3 to 4.5 inches in diameter to a depth of 102.5 feet.

A 300-horsepower Cat C9 engine can be configured to meet emissions standards worldwide, and the unit utilizes the Cat 315E excavator undercarriage. The compressor, which features widely variable air control, produces 350cfm at 150psi. Two different rock drill choices include the standard rock drill, the HPR5123, which uses 45- or 51-mm drill rod, and the HPR4519, which uses a 45-mm drill rod.

The cab is isolator-mounted to minimize vibration, and pressurized to reduce dust infiltration. The control system features touch screen navigation for Drill Assist, rearview camera, tram, water, rock drill auto-lube, alerts, drilling and target depths, penetration rate, machine performance, total hours and service. A high-resolution display uses simple icons to aid navigation and control, and it shows constant performance monitoring of pressures, rotation and hole depth. Also, a depth indicator ensures all holes are drilled to the planned depth to promote a better floor, reduce secondary blasting and reduce equipment wear, Cat says.

The MD5075C incorporates additional technology to assist in operations and equipment management. Drill Assist monitors main hydraulic systems and automatically adjusts to pre-programmed parameters. It incorporates anti-jam, anti-plunge and anti-plug, which combine to boost productivity and increase the life of the drill string.

Cat Track Drills are equipped with the Cat Monitoring System, which monitors critical engine functions and will de-rate the engine to protect itself from damage if needed. When critical conditions arise, the monitor displays warning lights and sounds alarms.
